WEFT STOP-MOTION FOR LOOMS.

SPECIFICATION forming part of Letters Patent N 0. 393,935, dateiDecember 4, 1888.

Application filed October 3, 1887.

To all whom it' may concern.;

' Be it known that we, VILLIAM TAYLOR and CHRISTIAN G. SAALFRANK, ofProvidence, in the county of Providence and State of Rhode Island, haveinvented certain new and useful Improvements vin lVeft Stop-Motions forLooms, of which the followingl is a full, clear, and exact description,reference being had to the accompanying drawings, forming part of thisspecification.

This invention relates to mechanism for stopping the running of a loomupon the failure of the proper supply of the weft or lling in the loom,whether the failure be due to thel'n'eaking of the weft or the depletionof the same from the shuttle.

The object of our invention is to provide an efficient and neatstop-motion mechanism which will promptly effect the stopping of theloom upon the absence of the weft from its proper position as the laybeats up.

To the aforesaid purpose our invention consists in the novel andpeculiar arrangement and constructionof the several parts of themechanism, all as hereinafter fully described.

In the accompanying'drawings, illustrating our invention, Figure 1 is aplan view of our improved stopmotion, part of which is mounted on thelay of the loom and part on the breast-beam, the latter part beingindicated in broken lines. Fig. 2 is an enlarged detail view of aportion of the stop-motion shown in side view; and Fig. 3 is a view ofthe parts shown in Fig. 2, the view being taken at right angles thereto.Fig. 4 is a plan view of the parts shown in Fig. 2. Fig. 5 is a sideview of another form of cam used in the mechanism, together with theother adjacent parts.

In the said drawings like numbers of reference designate correspondingparts throughout. A i

Referring to the drawings, the number 6 designates the lay of the loom,and the broken lines 7 indicate the breast-beam. The swinginglocking-dog 8 is provided with the bearings 9, which are journaled inthe bracket l0, secured on the bed-plate 11. The detectorfork 12 issecured by means of the screw 13 to the locking-dog, the under face, 14,of which ings.

is formed inclined, and over this inclined face slides the cam 15, whichserves to elevate the dog and raise the detector-fork into its highestposition, so that the fork may clear the shuttle when passingthereunder. The detector-fork is disposed transversely of the lay` inwhich is formed the slot 33, which the fork may fall into in order tolower the dog sufficiently to look the cam 15, as hereinafter described.The cam 15 is pivoted at 1G to the 6,0 bed-plate 11, and is providedwith the segmental slot 17, which works over the stud 18, fixed to thebed-plate.

The cam l5 is provided with a p'rojection or shoulder, 19, which isengaged by the locking-dog S, when the latter is permitted to fall intolow position, through the absence of the weft and its consequent failureto vhold the attached detector-fork elevated, as shown in Figs. 2 and 3.In this position the dogSlocks 7o the cam 15 against moving in onedirection.

The stop-motion rod 20 is hinged to the cam 15 by the bolt 21, and theother end of the rod .is passed loosely through the bracket 22, formedwith slot 23, which is shown in broken lines. 'The extreme end of thisrod is formed with an enlargement, 24, to prevent the rod Jfrom beingwithdrawn from the slot. The spring 25 is placed about the rod, and oneend thereof abuts against the adjustable stop 26, 8o secured on the rod,while the other end of the spring bears against the slide or washer 27,which engages with one face of the bracket .Y

The shipper-bar 28 is Inounted in the hangers 29, which are fastenedupon the under face of the breast-beam 7, and the bar is capable ofbeing reciprocated endwise in its bear- One end of the shipper-barengages the shipper-lever 30, (shown in cross-section in.

1,) and 31 is an adjustable stop, mounted 9o on the bar and designed tobe engaged by the foot 24 of the rod 20 and pushed thereby sufficientlyfar to ship the driving-belt (not shown) in order to stop the loom,whenever the absence of the weft 32 (shown in Fig. 1) allows 95 thedetector-fork to lower the dog S, so as to lock the cam 15, which thenbeing fixed will push the rod 20 through the slot in the bracket 22, inan obvious Inanner, into engagement with the stop 31 as the lay movesforward. Ioo

1o which is moved by the motion oi' the lay because ot' the resistanceottered to the rod :20 by the spring 25. The dog thus escaping theprojection on the eam, it eannotI lock the cam, so that the rod 2t) isnot moved far enough to I5 engage the shipper-bar; but when the wet't 32and adapted to engage the weft, the eam for is broken or is not inproper position the dog loeks the cam, and the beating up of the laypushes the rod 2t) into engagement with the shipper-rod and stops theloom as above de- 2o scribed.

The bed-plate ll is to be fastened at a suitable place along the lay andupon the V["ace thereof opposite the breast-beam, as shown in Fig. l.

Having thus described our invention, we elaim as new and desire toseeure by Letters Patent-- a projection tor engaging the dog,whereby thelattermay lock the cam, a shipper-bar, and a stop-mot ion rod hinged byone end to the said eam t'or operating the latter and engaging by theother end the shipper-bar, and a fixed slotted braeket through the slotot' which the other end ot' the said rod takes, the rod being providedwith a spring to resist the motion imparted to the rod by the movementot' the lay, substantially as and tor the purpose herein described.

ft. The eombination, as hereinbefore set forth, with the lay t'ormedwith a slot; to reeeive the detector-t'ork, olf a swinginglookingdog andthe detector-t'ork mounted thereon raising the dog and provided with aprojection or shoulder by meansot' whieh the dog l may lock the cam, ashipper-rod provided with a stop, a stop-motion rod hinged by one end tothe eam and (aigaging bythe other end the stop on the shipper-bar, aslotted bracket i tixed to a stationary pal't ot' the loom, and the endot' the stop-motion rod loosely passing' through the slot ot' thebracket, a slide or washer working on the rod and abutting against thebracket, a stop tixed to the rod,

l. The eombilmtion, as hereinbefore set forth, with a swinginglocking-dog and a dei 3o teetor-fork mounted thereon, ol a eam t'orelevating` the fork to its highest position, the said eam provided withmeans for engaging the loeking-dog when the fork detects the absence ofthe weft, lthe shippenbar, and the stop-motion rod provided with aspring and intermediate the said bar, and cam, whereby i ted braeket 22t'or reeeiving the end ot' the the shipper-bar may be moved by the rodupon the loekingot' the cam by the loelzing-dog, substantially as andt'or the purpose herein deseribed.

2. The Combination, as hert'linbetore set forth, with the lay, ot' theswinging loekingdog and the deteetor-tork mounted thereon, a Cam formoving the dog so as to elevate the fork into its highest position andprovided with a projeetion for engaging' the dog, whereby the dog mayloek the cam, a shipper-bar for etli'eeting the shipping ot` the belt,and a stop-motion rod hinged to and operating the eam and engaging theshipper-bar when the cam is locked by the dog, and a spring mounted onsaid rod to resist the motion imparted to the rod by the movement of thelay, substantially as and forthepnrposeherein described.

3. The combination, as liereiiibetore set t'ortl1,with the lay, ot' theswinging locking'- dog and the detector-fork mounted thereon,

a eam for raising the dog and provided with and a spring intermediatethe stop and the slide on the rod, substantially as and t'or the purposeherein deseribed.
